NewzNZB has been online since 2012. The site runs on custom software and boasts clean releases and an absence of spam. You’ll need an invite to sign up, and their membership plan is more expensive than some of the other options out there. Nonetheless, NewzNZB is a fine site that offers quite a few spam-busting and privacy-enhancing features.
NewzNZB has a custom-made interface, but it is also compatible with popular downloaders. The website is secured with SSL technology, and it has no advertisements on the website.
